Interpretation: The percent yield of the given reaction is to be stated.
Concept Introduction: According to the law of conservation of mass, the mass can neither be created nor be destroyed. Every reaction must be balanced. With the help of the balanced equation, the limiting reagent can be found and in accordance with it, the amount of product can be calculated.
Answer to Problem 38LC
The percent yield is 70.67%.
Explanation of Solution
The reaction is given as follows:
The mol of Al is calculated as:
According to the balanced equation,
The mass of copper is calculated as:
The theoretical yield of copper is 6.58 g and the actual yield is given as 4.65 g. The percent yield is calculated as:
Hence, the percent yield is 70.67%.
